The HK79 underbarrel grenade launcher has been developed by the famous company Heckler-Koch from Germany. This add-on launcher was mounted on 7.62mm G3 and 5.56mm HK33 and G41 rifles, developed by the same company, and is (or was) in service with armed forces of Germany, Norway and few other countries.

HK69 is a single shot, breech-loading add-on weapon with rifled barrel. The barrel is made of steel, and is hinged to the launcher frame at the front,  to be tipped down at the rear for loading and unloading. The single-action firing mechanism has manually cocked action and manual safety, located at the rear of the launcher. The button-shaped trigger is located at the left side of the launcher frame, above the barrel. Rear sight of ladder type is marked from 50 to 350 meters, and is clamped onto the top of the host rifle receiver. The HK79 can fire all types of 40mm low-velocity ammunition, including the HE-FRAG, HE-DP, smoke, illuminating and various less-lethal (tear gas canister, rubber baton) rounds.
